Is there scratching coming from your ceiling at night? Does a strange smell waft through the house when the furnace kicks on? You might have unwanted guests living in your HVAC system.
Mice, rats, and squirrels view air ducts as safe, warm, and secure highways through your home. But their presence is more than just a nuisance—it's a direct threat to your family's health and safety.
Signs of Infestation
Rodents are stealthy, but they leave clues.
- Noises: Scratching, scurrying, or squeaking sounds, especially at night. The metal ducts amplify these sounds.
- Odors: A strong smell of ammonia (urine) or a rotting smell (deceased animal) coming from vents.
- Debris: Finding small pellets (droppings) blowing out of vents or gathered near registers.
- Reduced Airflow: Nests built from insulation can block ducts entirely.
Are They Dangerous?
Absolutely. When rodents live in your ducts, every time the AC or heat runs, air blows over their waste and circulates into your rooms.
1. Disease
Rodents carry hantavirus, salmonella, and leptospirosis. Breathing in particles of dried urine or droppings can transmit these diseases to humans.
2. Parasites
They bring friends: fleas, ticks, and mites. If the host animal dies in the duct, these parasites will migrate into your home looking for a new host (you).
3. Fire Hazard
Rodents love to chew. If they chew through electrical wires or compromise the furnace components, it can cause a house fire.
What To Do (The Process)
Getting rid of the rodents is step one, but the job isn't done until the biohazard is removed.
Step 1: Extermination
Contact a licensed pest control professional to trap and remove the animals. Do not use poison inside ducts, or the animal may die in an unreachable spot, causing a terrible odor for weeks.
Step 2: Exclusion
Find how they got in. Seal entry points in the attic, crawlspace, or roof vents.
Step 3: Professional Duct Cleaning & Sanitation
This is where we come in. Once the pests are gone, you cannot leave the droppings and nesting material behind.
- We use negative pressure to safely suck out droppings without contaminating the home.
- We remove insulation nests.
- We apply a strong hospital-grade disinfectant to neutralize bacteria and viruses.
The Critical Step: Sanitation
Simply observing that the "mice are gone" isn't enough. The bacteria remain. Ensuring your ducts are treated with an EPA-registered sanitizer is the only way to ensure the air is safe to breathe again.
Don't Wait
If you suspect rodents in your system, this is an emergency. Protect your health and your home. Call 101 Local Duct Cleaning immediately after pest control services to restore your home's hygiene.
